SAFETY Gas-BURNER.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed. April 22, 1912. Serial No. 692,403.

To all whom it may concern:

Be it known that I, CnAnLns ERNEST Brains, a subject of .the King of Great Britain, and residing at Toronto, Ontario, Canada, have invented certain new and useful Improvements in Safety Gas-Burners, of which the following is a specification.

My invention relates to improvements in safety gas-burners, and the object of the invention is to provide a device which will prevent the escape of gas in case the tap should he accidentally turned on, and will also automatically shut off the gas if the flame be extinguished through any cause whatsoever.

A still further object of my invention is to simplify the construction of this class of gasburners so as to reduce the cost of manufacturing the same, and also to produce a gas-burner which will be positive in its operation.

Broadly considered, my invention consists of a casing designed to be attached to the gas-pipe, the burner being carried by said casing; a spring-controlled thimble c0- acting with a member to control the passage of gas out of the pipe through said thimble; a spring-controlled bolt connected to a lever 'to which is connected a member positioned in the path of the heat generated by the burner, the said member being constructed of material which will readily expand and contract according to the change in temperature and operate said lever and its bolt at certain times to insure the cut off of the.

supply of gas, means being provided for operating said thimble to admit the flow of gas therethrough, as hereinafter more par ticularly explained.

Figure 1 is a vertical central sect-ion through my gas-burner, showing the same combined with the ordinary upright burner tip. Fig. 2 is a side elevation, partly in section of the casing and the thimble, showing the mechanism for operating said thirnble to turn on the gas. Fig. 3 is an end elevation of the operating lever and its support connected with the bolt for locking the thimble in open position. Fig. 4: is a plan. view of the lever for operating the thimble. Fig. 5 is a side elevation of my burner showing the same adapted for use with an inverted incandescent burner, and Fig. 6 is a plan View of the member which expands and contracts according to the change in temperature.

In the drawings like characters of reference indicate corresponding parts in each figure.

A is a gaspipe and B the ordinary tap therefor.

C is the casing of my burner and the same is integrally provided with a coupling D which is internally threaded to screw over the threaded end of the pipe A.

E is the cap for the casing C, and the same has threaded union with said casing as shown at F.

Mounted within the casing O is the thi1nble G. The casing C is preferably circular in shape, and consequently the flange ll carried by said thimble is circular in shape and easily fits against the inner wall of said casing.

Having threaded union with the coupling 1) is a nipple 1., The bore J of the casing C fits around said nipple so that the aid casing may have movement on said nipple. K is a nipple carried by the thimble G, and the same operates within the bore L of the'cap E. that the said thimble G has movement on the nipple I and in the cap E. 2 is a nipple carried by the cap E on which is screwed the burner 3 provided with the ordinary burner tip 4:.

The thimble G is provided with a diaphragm 5 which is provided with a plurality of holes 6.

The construction of the nipple K provides an annular shoulder 7, and resting against this annular shoulder, and surrounding the nipple K is a coiled spring 8, which rests against the flange 9 of the cap E.

Integrally formed with the casing G is a.

housing 10. Operating within this housing is a bolt 11, the inner end of which operates through the hole 12 formed in the casing C.

18 is a pin or flange carried by the bolt 11, and surrounding this bolt and positioned between the said pin or flange 13 and the cap 14 which closes said housing, is a coiled spring 15. The bolt 11 extends through a. hole in the cap 14 and it is pivoted by the pin 16 to the lower end 17 of the lever 18.

It will therefore be understood The lever 18 is pivoted by the pin 19 to the stationary arm 20 which is secured by the screw 21 to the cap E. 1

22 is a stationary arm secured by the screw 5 23 to the cap E.

In order to make the casing G symmetrical in appearance a dummy casing 24 is carried by the casing C, and through the extension 25 of dummy casing 24 passes a pin 26, which passes through the lower end 27 of the arm 22.

In order to permit gas to pass through the nipple I, the lever 28 which is pivoted by the pin 29 to the lug 30 carried by the casing 0, is operated by the chain 31, and as the lever 28 is provided with a bifurcated end' 32, the arms 33 of which embrace the extension 24 of the thimble G, and are positioned underneath the annular flange 25 of the said thimble, the said upward, thereby withdrawing the needle valve 36 carried by the diaphragm 5, from the hole 37 formed in the top 38 of the nipple I. The gas escapes through the parts before described and is of course ignited.

39 is a member which will readily expand and contract according to the change in temperature, and this member is secured by the screw 10 at one end to the fixed arm 22, and by the screw 41 at its other end to the lever 18. As the said member 39 is in the path of the heat from the flame, it will immediately expand sufficiently to permit the spring 15 to drive the bolt 11 inward to so move the nose underneath the flange The flange H was of course moved above the bolt 11 by the described movement of the thimble G, and it will therefore-be understood that the said thimble will be locked in the described position by the bolt 11. The locking of the said thimble will occur Within a very short time and before the operator ceases pulling on the chain 31. If the gas be turned ofi by the tap B, or blown out, the member 39 will immediately contract, and through the medium of the lever 18, the bolt 11 will be withdrawn from engagement with the flange H and therefore the spring 8 will immediately move the thimble G back to normal position and so close the hole 37 by the valve 36.

From the foregoing part of my specification it is self-evident that the described gas-burner will automatically cut off the escape of gas from the pipe A when the flame is extinguished.

In Fig. I show my for use with an inverted incandescent burner. In this form of my invent-ion the arms 220 and 221 project downward. The lower end of the arm 221, and the lower end of the lever 181 carry the member 391 which will expand and contract under the influence of the temperature. The member 65 391 is constructed of two horizontal bars gas-burner adapted thimble is moved within said casing;

0 and d, which are connected together by a ring-shaped section 0 through which passes the tube f which supports the mantle g. The section 6 is divided as shown at It so that expansion and contraction may have full play.

From the foregoing specification it will be clear that since the flanges H and 35 extend around the thimble G, the said thimble is free to turn on its longitudinal axis without in anywise impairing the efliciency of the burner. The said thimble really constitutes a spring controlled valve within the casing C which operates to control the flow of gas from the pipe A.

Various changes in construction may be made without departing from the spirit of my invention as set forth in the annexed claims.
